BALTIMORE – The use of ex vivo lung perfusion (EVLP) may allow for the safe transplantation of lungs preserved for more than 12 hours, according to a study presented at the annual meeting of the American Association for Thoracic Surgery.
A research team at the University of Toronto evaluated the outcomes of transplant patients who received a lung with a preservation time of over 12 hours between January 2006 and April 2015 and compared them to the general lung transplant population. Median hospital and ICU length of stay were similar between the two groups, and Kaplan-Meier survival curves between the two groups did not show any difference. Preservation time, donor PO2, and use of EVLP were not significant variables affecting survival.
Dr. Bartley P. Griffith, chief of cardiac surgery at the University of Maryland, Baltimore, and a discussant on the paper at the meeting, said that the findings of the study open up the possibility of a more “planned” approach to transplantation.
“Anything that not only extends preservation time, but perhaps even improves quality of preservation, would be a godsend,” Dr. Griffith said in a video interview. He cautioned that the “devil is in the details,” and that the data had to be examined closely. Nevertheless, Dr. Griffith said transplant surgeons should be grateful for the important work done by the University of Toronto team.
Dr. Griffith reported no relevant financial disclosures.
